chore(docs): refresh the descriptor catalog pointer
Correcting the cold-resume module contract added one JSDoc line above SubagentDescriptorData, but the generated persistence catalog still linked the durable subagent/descriptor event payload to descriptor.ts line 36. That left a dead source pointer and made the repository documentation gate fail even though the catalog content itself was otherwise current.
Regenerate docs/persistence-catalog.md so its source link follows the declaration to line 37. This is a generated-reference correction only: it does not change the durable event vocabulary, payload shape, or runtime behavior.
Validated with pnpm run verify-persistence-catalog and git diff --cached --check; the generator reports the catalog is up to date.
